The T8122 is a Trusted Processor Interface Adapter that mounts directly behind the T8122‑compatible T8110B or T8111 TMR processors in the T8100 chassis. This T8122 exposes serial, IRIG‑B, and diagnostic ports to external systems. With MODBUS Master enablement and precision time synchronisation, the T8122 turns the Trusted controller into a flexible industrial communication gateway.
Direct chassis‑mount eliminates external cabling and reduces installation effort.
Enables MODBUS Master operation, allowing the Trusted system to actively poll field devices.
Supports IRIG‑B time synchronisation for accurate event time‑stamping.
Provides fault/fail relay contacts for both Active and Standby processors.
Hot‑swappable for maintenance without system shutdown.
3 RS422/485 serial ports (Port 1: 2‑wire; Ports 2 & 3: 2‑ or 4‑wire).
IRIG‑B122 and IRIG‑B002 time‑code inputs on one connector.
Fault and fail relay outputs for Active and Standby processors.
PSU shutdown monitor inputs.
MODBUS Master capability (requires T815X Communication Interface).
Dual (enhanced) Peer‑to‑Peer support.
Routes internal TMR processor signals to external RS422/485 ports for DCS, SCADA, and peer‑to‑peer communications.
Provides IRIG‑B time synchronisation inputs (B122 amplitude‑modulated and B002 pulse‑width modulated) to align the Trusted system with plant‑wide clocks.
Offers fault and fail relay contacts (normally closed, open on system fault or processor shutdown) for external alarm or interlock integration.
Accepts volt‑free contacts on the PSU shutdown monitor to signal power‑supply failures to the application.
Enables MODBUS Master operation (when paired with T815X), allowing the Trusted processor to initiate queries to slave devices instead of only responding as a slave.
Q1: What is the T8122 used for?
The T8122 is a rear‑mount adapter that provides external communication access to Trusted TMR processors for DCS, SCADA, and time‑synchronisation links.
Q2: How does the T8122 differ from the T8120?
The T8122 adds MODBUS Master enablement; the T8120 offers basic serial and relay connections only.
Q3: Does the T8122 support hot‑swap?
Yes, the T8122 can be replaced without powering down the system in redundant configurations.
Q4: What IRIG‑B formats does the T8122 accept?
The T8122 accepts both IRIG‑B122 (1 kHz AM) and IRIG‑B002 (pulse‑width modulated at 100 bits/s).
Q5: Is a Communications Interface required for MODBUS Master?
Yes. The T8122 enables the option, but a Trusted Communications Interface (T815X) is also needed for full MODBUS Master functionality.
